Maintenance
Bright-metal maintenance
To remove road tar and insects,
use a tar remover, not a scraper or
other sharp object.
To protect the surfaces of bright-
metal parts from corrosion, apply a
coating of wax or chrome preser-
vative and rub to a high luster.
During winter weather or in coastal
areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
Underbody maintenance
Road salt and other corrosive chemi-
cals are used in cold weather states to
melt snow and prevent ice accumula-
tion. If these chemicals are not regu-
larly removed, they will corrode the
vehicle underbody and over time dam-
age fuel lines, the fuel tank retention
system, the vehicle suspension, the
exhaust system, and even the body
frame.
Wash the undercarriage of your
vehicle regularly during the winter
and whenever your vehicle has
been exposed to such salts or
chemicals.
Do a thorough washing of the
undercarriage at the end of the
winter.
Use professional service techni-
cians or governmental inspection
stations to annually inspect for cor-
rosion. Immediately seek an inspection of
your vehicle if you become visually
aware of corrosion flaking or scal-
ing or if you become aware of a
change in vehicle performance,
such as soft or spongey brakes,
fluids leaking, impairment of direc-
tional control, suspension noises
or rattling metal straps.
